violence/psychology

In the early ages of mankind, violence was a way of establishing dominance and settling disputes, because humans didn't have a better way of communicating. I think it is absolutely ridiculous that we still have to resort to it nowadays in order to get our point across. It doesn't make any sense that the only way countries can settle an agreement is to bomb the hell out of eachother instead of talking it out, the only way we can create a sort of superior feeling for ourselves is to create a desperate situation in another place. Perhaps in the days when early humans were still using rocks to fight it was more understandable, but I just don't understand why, when the world has an exceptional capability to use language to communicate, weapons of mass destruction are still necessary. I think violence should only be resorted to as a means of defense, but if the opposing side hadn't used violence in the first place, it wouldn't be necessary at all.

What good is psychology for the world? I don't think I've fully comprehended yet the subtle benefits that understanding human psychology gives us. Perhaps by understanding the human mind better, we can understand eachother more and we become less self-centered in our daily lives. We can also become happier with ourselves by going to a therapist who can help you work out problems you didn't know you had.
